Orchidaceae species in the forests of the National Park “Udege Legend”.

Abstract

A detailed-route survey of forests of the National Park “Udege legend” revealed the location of 7 species of the Orchidaceae family (Cephalanthera longibracteata, Cypripedium macranthon, C. calceolus, C. ventricosum, Liparis japonica, Epipactis papillosa, Oreorchis patens), 5 of which are included in the Red Data Book of the Russian Federation. In the park, one of the largest Cephalanthera longibracteata populations in Primorsky Krai, numbering more than 120 individuals, was found. A point-based account of Orchidaceae showed that their main populations are located in an oak formation in which crown and ground fires should be eliminated. Findings of representatives of the Orchidaceae family in the National Park supplement the information on the distribution of protected species in the territory of Primorsky Krai.
